It seems terribly intimidating and almost impossible at times—but don't give up! Every good Irish traditional musician learned to do it at some point or other, and we can all relate to your frustration. It's especially hard if you began by learning off of music (the dots, as many players call them). You'll find that most experienced musicians are much more forgiving of your learning curve than perhaps you are yourself, so don't let your embarrassment make you give up.
